Camera Follow Smoothing Calculator
Calculate frame-rate-aware exponential interpolation for camera following.
Your inputs
Calculation results
Formula & assumptions
Blend per frame = 1−2^(−dt/half-life); time to 1 percent remaining = half-life × log₂(100).
Values use the specified units. Calculations use floating-point arithmetic. Check input measurements and formula assumptions before applying the result.
Compare your scenarios
Save up to five results to compare changes side by side. Scenarios stay in this tab until you clear or reload it.
Using Camera Follow Smoothing Calculator
Calculate frame-rate-aware exponential interpolation for camera following.
- Enter half-life, frame duration, initial distance using the units printed under each field.
- Choose Calculate, or enable live updates. Review the result labels and formula assumptions.
- Save scenarios to compare up to five variations, then copy the report or download JSON or CSV.
Example
Half-life: 0.2 seconds Frame duration: 16.6667 milliseconds Initial distance: 100 units Blend factor: 0.056125796 Remaining after one frame: 94.38742 Time to one percent · seconds: 1.3287712
Questions & answers
What does Camera Follow Smoothing Calculator calculate?
Calculate frame-rate-aware exponential interpolation for camera following.
Which units should I enter?
Half-life uses seconds. Frame duration uses milliseconds. Initial distance uses units. Convert values to these units before calculating.
Which formula does it use?
Blend per frame = 1−2^(−dt/half-life); time to 1 percent remaining = half-life × log₂(100).
What does the included example show?
Half-life: 0.2 seconds; Frame duration: 16.6667 milliseconds; Initial distance: 100 units. Result: Blend factor = 0.056125796; Remaining after one frame = 94.38742; Time to one percent · seconds = 1.3287712.
Can I compare different settings?
Yes. Save a scenario, change the inputs and save another result. Up to five scenarios are compared in this tab; they disappear when you reload or leave.
Can I export the calculation?
Copy the JSON report or download JSON and CSV with inputs, result labels and numeric values. Processing uses local JavaScript; no calculation request is sent to our server. Displayed values use up to 10 significant digits; exports retain JavaScript numeric precision.
